Find the forces per unit length on two long straight
Parallel conductors if each carries a current of 10A in the
Same direction and the separation distance is 0.2m?
Question Three: Magnetic Force between wires.
Three long parallel wires are 5 cm from one another. (Looking along them, they are at three
corners of an equilateral triangle.) The current in each wire is 10.00 A, but its direction in wire M
is opposite to that in wires N and P. Determine the magnetic force per unit length on each wire
due to the other two.

In the figure, four long straight wires are perpendicular to
the page, and their cross sections form a square of edge
length a = 15.0 cm. Each wire carries 7.00 A, and the
currents are out of the page in wires 1 and 4 and into the
page in wires 2 and 3. In unit-vector notation, what is the
net magnetic force per meter of wire length on wire 4?
